Abstract: Tischtschenko condensation of aldehydes is used to remove aldehydes from dry ketone-containing streams. The tischtschenko condensation is used to condense the aldehydes into esters whose boiling points are significantly different than the ketones, greatly simplifying the separation of the esters from the ketones. An organic extraction step is used to obtain a substantially dry ketone containing stream. One particularly preferred class of extraction solvents is selected from the group consisting of butane, pentane, hexane, heptane, octane, nonane, decane and mixtures thereof. In particularly preferred embodiments, the Tischtschenko reaction is used in the context of aqueous-phase catalyzed olefin oxidation to ketones. The aldehyde to ester condensation permits easy and efficient removal of the aldehyde analogs of the desired ketones.

Abstract: A plow arrangement is disclosed for inserting continuous lengths of foldable conduit in the ground. A plow forms a cavity in the ground for receiving the conduit. Folded conduit is conveyed from a reel to an inlet end of a feeder or boot. As the conduit passes through the feeder, it is unfolded. The feeder discharges the unfolded conduit horizontally behind the plow. Soil lifted by the plow falls around the unfolded conduit constraining it to its unfolded configuration. A vehicle advances the plow and feeder through the ground. The feeder includes a surface for engaging the base of the conduit and guides for engaging the top. The surface and guides converge adjacent the outlet of the feeder to unfold the conduit passing inbetween. Further the surface and guides have arcuate portions that bend the conduit about its apex to urge it to its unfolded configuration.
